    I started at 25 yards to get close and then zeroed at 50.

    It varies with access and guns. I usually bore site if I can and then get to a range. If I am stuck with the indoor 25 yard I will zero there and adjust to 100 on the charts. If I am at the outdoor 100 yard, I will set my targets at 100 yards and place a golf ball on the back stop mound. I am at the golf ball and watch the impact in the dirt. Adjust and go to targets.
    22lr I will zero at 25 yards which is good to 60-70 yards depending on ammo.

    Not really gunning for a specific distance. I'm shooting 5.56 and figure the 50 yard zero is pretty damn good out to about 250 yards. Besides I'm only using an eotech and fts 3x magnifier so anything beyond that would be a tough shot anyway.

    On my ar15 its 100 yard zero for the acog since the bdc is graduated for that, and 50 yard zero for the iron sights.

    My 308 WAS zeroed for 100 yards but its not mine anymore and ive likely lost my supressor too :mad: the wife decided they were both hers and i cant have my nightforce scope back either.

    She did say i could get a colt 901 if i could find one but i wasnt getting the savage back. When i do she isnt touching it. Not even a little.

    Jon my wife does not hunt and shoots rarely so mine are safe--so far. Like to bore sight if possible and go from there. If not then I start close and go to 100. My hunting shooters are all zeroed at 220 yds. That way I can "Kentucky windage" easily from there. Used to have all my "dope" taped to stocks but that was a long time ago when hands were steady and eyes sharp. Us old farts have to be content with minute of barn door--well not quite--lol.

    You don't need a bore sighter. Each brand of ammo will have a different zero. I just plop the gun onto a bag of cat litter, get it down into it a little to hold it still, shoot three shots into a target and then adjust my sight to the center of the three holes. Then it's zeroed for that brand of ammo.

    You might have trouble benching a gun with a 30 round mag. There are 5 and 10 round mags available. If you're only using it for zeroing you can get a cheap one.

    Mechanically zero your sights.

    This means the flat portion of the front sight post flush with the sight housing and the rear peep centered. Should be pretty close to 25 yard zero.

    With a scope you need to know how many rotations it takes to go from stop to stop divide by two and center the elevation and windage. Then you can bore sight. Remove bcg look down barrel at a distant target around 100 yards out, and see if the scope or irons as case may be line up close with picture down bore. Adjust sights till it matches the bore.

    You dont need electronic bore sighters.

    In this example, if I a trying a 200 zero on my 100 yard range, I use two or three check points.

    25 yard range, I adjust for about 3/8 below POA
    35 yards ~ zero
    100 yards s/b ~ 1.5 above POA

    This get's me satisfactorily close for when I can get to a 200 yard range.
